Intended working of Data retrieval

• Parameter 1 is ignored and can contain anything but " KSTART " (see Intended working of key selection)
• Parameter 2 is ignored.
• If applicable, parameters 3 and further contain an actual value for the Formal parameters of the Entry
• Position in the database (file) using the values passed in the parameters 3 and higher.
• Read all records from the database (file) that are identified by the values passed in the parameters 3 and higher (read by key).
• Return every record that is read to ITP using a call to ITP's ISNDDTA program

The data retrieval functionality is always required for an Entry.
